To all ZITIZO/H it i'i i (om-xvii:

Be it known shat l, .Axounw a citizen of the liiiiteil States of iiiiieriia, and a re limit of the city of :jt. Louis, State of Missouri, have invented a certain new an-l useful liiiproveinent in NiitLoe-hs, of which the l" llowing is a full, clear and exac't description. reference being had to the aecoiiipaii ving ilrawiiigs, forming a part of this specification.

My invention relates :0 iii-iprorei'neiits in nut locks. one of ihe oijects JOlli in provide a shu fle and iiiex ensive h ssing Ge '1 ice for scouring a nul to a bolt or other threaileil ineniher. llie locking device is also adapted to he iiseil ii'i loehing a set collar to a shall W. A Uni-:1: r,

iiiuiihei' I the invention is to pro- (lane a nut in :iiiui iieil to loel; -.1 nut in the threails or an orilr-i bolt; the locking dei'iee wing preli-rai ly a screw sereweil ate :1 iiiii illii'l ilklil L to interlock with the ilireails of he bolt to which the nut is ap plied.

(,llQ iiiil-lieii1gpi'o \iihiil with a screw i iriaiileil iolt receiving opening ul also with a screw tlii'eaile .l opening for ihe reception ol a locking; screw L. 'll e erew lhi'eaileil openings in the nut are orei'erahl i' i'ornieil sulistaiitially parallel wiih *ach other. Zlllil {he holt receiving openin is in coiiiiiiiurination with the olher screw threaileil opening. lhe locking screw C is DI'OVlilLll with a siil stantially flat face 1 iiilagii'uil to lie directly opposite the bolt as Shown in Fig.

lsei'oi'e. a i ilyiiig' the nut to El bolt the loiili'iiig screw C is screweil into the out by means oi a siri'iwv driver or other suitable tool. the looking screw l have shown heing pioi'iihil with a ii li'h l'or ilie 1rce ti('in of a screw driver. While the nut is lMllig screwed onto the bolt the locking screw oczii'e einl eihleil in the shaft.

in Fig. l3." :iiiil Fig. Y, I have shown the locking screw (1' a iplieil to a set .eollar A, llll\,l a shaft 13. Th set collar is a rotatable nieiiiher Uiill'lSllUilkllill to (he out A. and it 1J1'()\l(l0(l with. a tiii'eail'eil opening coinniiinieaiiii with the. shal't receiving opening in the sol collar. The locking screw C [Ui'iiiiiil with a llat face 1 adapted to lie ilirectl opposite a llat face of the shaft as shown in Fig. IV. 'hen the, set collar is ailjiistoil lo the ilLSlFCLl PUSltli'ln on the shaft B, the loi-liiiig screw is turned slightly to force its sharp coi'nurs into engagement with the (lat lace ol' the shaft, anil the set collar is then turned to impart a rotary nioren'ieiit to the locking si-i'ew, th'erehy turning: the liil'hlllfj v crew to the position showii in Fig. V wherein its screw threads The set coll-.11 is the reception threaded openings beingsubstaitnilly parsecured to the shaft. In

means of a suitable wrench to locate e locking screw directly opp cite the Hat face 01 the shaft, and the locking screwmay [then be adjusted, if necessary, by means of screw driver, to the position shown in Fig. EV thereby unlocking the set collar i'rom the shaft.

I claim: i

1. In a device of the character described, a bolt having a screw threaded end, nut fitted to said he said nut beingorovided with a screw ti ded bolt receiving open-- ing and with a screw threaded opening for of locking screw, said screw thus vory firmly removing the collar it isturned fallel witheaeh other and the bolt receiving opening being in coninr ication with the other screw threaded opening, and a looking screw screwed into the nut, ing screw being provided with screw threads adapted to overlap the screw threads of said bolt,- and said locking screw bemg' provided with a fiat face adapted to he directly opposed to the threads of said bolt.

2. In a device of the character described, a bolt having ascrew threaded end, a nut fitted to said bolt, said nut being irouided with a screw threaded bolt receiving-opening and with, an opening for the reception of a locking; screw, said openings being sub stantially parallel with each other and the screw threaded; boltfreceiving opening be ing in communication with the other opening, andajlocking screw seated in the last mentioned opening, sai d locln'n screw being provided with. mutilatedsorew threads e2;-

tendin nartiallv around its nerioher and b .1 r l adapted to overlap and bear against the screw threads of said bolt to prevent the nut from turning on said bolt, the face of said locking screw between the ends ofits mutilated threads being; closer to the axis of said locking screw than the outer points of said mutilated threads so that the locking screw may be adjusted. in the nut to permit the 'nut to turn freely on the bolt.

In a device of the character described,

oolt having a to id 2 reception threai d openi bolt rr aticn v. I other screw threaded 0' ing, and locl; ing screw screwed into the nut, said loching screw being llllO'E'ltlQCl w th mutilated I rear threads ext-e around its peripl y and adapted LO ow a and bear again. the screw threads of said bolt to UlQ'VQll 1e nut from tar on said bolt,'

the oi said locking w between the ends of its mutilated threads being closer to the of said .lockinn' screw than the outer points of said 1' ted thrzads so that the locking screw may be adjusted in the nut to permit the nut to turn lreely on the bolt. 7

i, A device of character descubed comprising a rotatable outer member having an opening; and also ha ii rew threaded o ening communicating with and substaiu tially parallel with the first mentioned open-- ing, a substantially circular innerinember insaid opening of the rotatable outer member, and a lock ng screw sore d into said screw threaded onemn said iockin screw bem! L. 1 h 1 c provided with mutilated screw tin "(is e):-

tending partially around its outer face and adapted to be forced into said substantially circular inner member to prevent the rotatable outer member from turning on said substantially circular inner member, the face otsaid locking screw between the ends ofits mutilated threads being closer to the axis of said locking screw than the outer points of said mutilated threads so'that tl'ie'locking screw may be adjusted in said rotatable outer member to permit the latter to turn freely on the substantially circular inner member.
